This commit adds a myriad of test cases to ensure the format and mount
and extend packages are working as expected

This was split out from pkg/format into its own package.
It has the ability to extend ext4, btrfs and xfs partitions.

This commit rewrites the mount package in Go.
It adds the ability to mount the by label, UUID or name.
It also fixes the automatic mount logic to check that a drive isn't
already mounted before attempting to mount it. This allows for multiple
uses of the mount pkg in a single YAML file.

This commit re-writes the format package in Go and adds the ability to
add partition labels and also specify either ext4, btrfs or xfs

These tests run individual and a mix of namespace stress tests
mostly around networking and unix domain sockets where either
the client or the server of socket echo application is run inside
a container in different configurations:
- different protocols
- short or long lived connections
- different levels of concurrency
Tests are only run if the 'kernel' label is specified and more
detailed tests are run if the additional 'kernel-extra' label
is specified.

The previous version just created a network name space which does
not allow us to also test additional namespaces, e.g. for unix
domain sockets.
This commit uses runc to create a fully namespaced container to
run a test in. It creates a container, configures the network
interfaces in the new network namespace before starting the
container.
A OCI config.json template is used and then customised for a
given test based on command line arguments.
Finally, instead of iperf, we use the socket stress test from
https://github.com/linuxkit/virtsock as it provides finer-grained
control over the traffic patterns (e.g. long lived vs lots of
short lived connections).

We should always pull and push linuxkit/alpine with content trust
irrespective of architecture, unless explicitly disabled.
Currently, we have to dance around various other issues on arm64,
which are now documented in the Makefile.

These contribute ~140M to the common image cache but do not appear to be used
by either the base system nor the sock-shop demo. They can/will still be pulled
on demands as necessary.

Bumps kubernetes and associated tools and images to v1.6.7 (from v1.6.1).
Updates weave from v1.9.4 to v2.0.1
Updates cni from a snapshot to v0.5.2. Note that the download location has
changed and the tarball no longer includes the `bin` subdirectory, so adjust
build to compensate.

Much smaller than the CentOS based one.
Note that ijc25/alpine-ssh has entrypoint==ssh.
Drop Compression=yes, this is used for local ssh so no point compressing (just uses CPU).

Remove `-publish` (which is currently Linux/QEMU specific) and replace with a
generic $KUBE_RUN_ARGS envvar. Usage:
KUBE_RUN_ARGS="-publish 2222:22" ./boot.sh
KUBE_PORT_BASE is thus obsolete and removed.

This follows the model in the hyperkit runner, although the options are
different.
The options are:
- `user`: the existing user mode networking (the default).
- `tap,«device»`: replaces the previous `-tap-device «device»` option.
- `bridge,«name»`: tap device on (preexisting) named bridge.
- `none`: No networking at all.
If not running as root then `bridge` mode requires host configuration
http://wiki.qemu.org/Features/HelperNetworking. TL;DR: you need to `chmod u+s`
the `qemu-bridge-helper` and to whitelist specific bridges in
`/etc/qemu/bridge.conf`.
Pass an explicit virtio nic and configure a random MAC since QEMU seems to use
the same one by default.
In the hyperkit runner the various `networking*` constants become
`hyperkitNetworking*` to avoid namespace clashes (e.g. for `None`). The QEMU
equivalents are `qemuNetworking*`.
Both hyperkit and qemu now support an explicit `-networking default` or
`-networking ''` to make scripting easier.

This is the same behaviour as the LinuxKit backend.
This populates /sys/class/dmi/id/product_uuid, which newer version of weave-net
appears to require.

The filesystem is supposed to be immutable, so do not try to make
a symlink; new versions of moby tool should add one anyway. But
try to make the directory a symlink points to, assuming that it
will be on a writeable filesystem.

Somewhere between the various updates yesterday the hash in
'versions.x86_64' went wrong and there is no image with hash
available on hub.
This commit updates the alpine base to the latest version and
thus rectifies the issue

This uses a more memory efficient copy, and gets us closer to
not having a shell in the base system if not required.
